`To all 'whom it may concern.'k y

Be lilt known that I, GLAsIo CAETANI, a citizen of Italy, residing at Kellogg, countyA of Shoshone, in the State of Idaho, ha ve invented certain new and useful Improvements,

in VaterJig's; and I do hereby declare the following to be a full, clear, and eXact description of the invention, `such as will enable others skllled in the art to which it ap-, pertains to make and use the same.

My invention relates to certain new and ofthe several screen compartments centrally of the' tails boards thereof and adjacent to said tails boards, a location which contributes to the general efficiency of the apparatus Abut which is diiiicult ofsatisfactory realization in practice.

In the accompanyingvldrawings, Figure l represents aA vertical section, and partial elevation cfa multiple compartmentr'water jig embodying my improvements, certain of the .compartments between the rst and lastof the series being omitted. as is 'indicated by the broken lines; Fig. 2 represents a verticalv section, on a plane transverse to-Fig. 1; Fig. 3 represents a top plan view of the parts shown in Fig. l; Fig. 4 represents, in per# spective, the tails board end of one of the screen compartments; and Fig. 5 represents in detail the construction of the dame partition and gate for the heads discharge.

Similar Aletters of referencew indicate similar parts throughout the several views.

Referring to the drawings, it will befnoted that'in its general structure, the jig is of the' Hartz type, comprising-a multiple series of units7 consisting of screen compartments A, hutch compartments B, piston Achambers C, pistons D, supported in a suitable frame E, the pistons being conveniently operated from a power shaft- S, common .to them all, through the/-intermediacy of the adjustable eccentrics a and piston rods F indicates the usual hutch box; ,Gr indicates'the supply receptacle for the ore to be classified, and H indicates the water supply box and c its feed' pipe. i The construction and mode of operati'oirof these parts require no description to specification of Letters Patent.

those skilled `in the art. I have found it convenient, in some instances, to employ as many as live or more of the multiple units (screen .'coinpartment, Vpiston chamber, and hutchcompartment, with their adjuncts) Abut it is evident thenumber employedmayl In f be varied within considerable' limits. the present drawings, I have chosen for illustration, theinitial unit, a portion of a second unit, and "a portion of the final unit' of a series;

For the purpose of separating and saving the slime contained in the feed and prevent--l ing it' from being carried off withvthe tailings, I arrange one or inor'e vertically adjustable partitions or slime dams Le transversely iacross These slime darns dip into the'jig-bed, and the lime water, therefore, banks up in the .manner indicated in Fig.. l, and flows out" through. the side discharge openings ci' shown in Fig. 3,' and which are to be provided with adjustable gates v2, into the 'l slimes collecting receptacle Il, from which Athey may besupplied for further treatment to any suitable slime table." rI`he slimes cannot pass below the second da1n-or partition e,

because they are prevented from so doing by the pulsating 4body ofwater rising through the jig bed. a.

In the first of the slime water sections I preferably arrange a splash partition f leaving an intervening free spacel for the ore to pass downY from the ore feed box to the Ascreen bottom, and between the partitions f and d -I place the wooden fioat g, which may conveniently be of the open, cellular struc- `ture shown. It thus floats on the top of the trapped slime water and has the function of breaking up the wavesv that would otherwise resultfrom the violent agitation of the slime water by the action of the reciprocating piston..

the screen compartment.

In carrying out that portion of my invenj tion which involves providing the several screen compartments with' a central dis-- charge for the heads, I proceed as follows:

Tothe tails board a of each of the coml part-ments,gl secure a block m which may be in two pieces, if desired, as shown in Fig. 4. By this expedient, I double the thickness of the partition between adjacent compartments, and provide means for accommodating the heads discharge pipe p, which, as shown in Figs. l and 4, may pass downwardly through. the pipe block ml and throughthe hutch compartment of the jig. At its upper end, the pipe m communicates witfh a dam-'discharge chamber having a suitable wall casing a", preferably. of metal,

Yflanged at 1', which casing rests within a recess formed in the combined tails board and' I' pipe block. i In frontI of the pipe block m 1s secured the liner-s, having a dani aperture and provided with a similarly apertured cover plate 1i; and an apertured gate v, adjustable to varying heights, permits the effective level of the dam to be suitably established. Finally, in front ofthe dam partition o'r liner s, is located the flanged counter-cupl w, which is releasably^secured -in position by the yoke whose screwthreaded ends pass through the cross-piece y l v and are provided with'tightening nuts.. As illustrated-in Figs. 1 and 4, the lower edge of the counter-cup 1s located `at the appropriate distance` above the upper'surface of the i l. In the final unit of the series,

the damdischarge chamber beyond the jig screen e to effect the classification desired.

- :A It will ajlso be noted that the upper edge of .25 the inclination of the upper edge 'of the tails the pipe block m is inclined to'correspond to board, as are also, the upper edges of the liners s, and z and, in practice, it dwill be preferable tocover the entire slope thus. provided, with a Wear plate o, as shown in Fig. I may carry c wall, asl indicated at r2, in which case the discharge pipe pf for the heads may pass downwardly outside the jig, as well as the final tailings pipe from thectailings boX R. Having thus described my invention, what I claim is:
